Restoration & Refurbishment- 5 Apr 2025
Where do I begin? So Alex and his team has pretty much renovated two flats including external work such as roofing. The work involved was quite challenging as the building has a lot of damp / mould / leaking issues. Alex’s attitude towards resolving every matter was exemplary. He would take his time to explain his strategy to tackle each and every problem in a very metholodical way. I have never seen anything like it. I am so pleased with Alex’s work and so are my tenants who live in the flats. I would highly recommend Alex, especially for tougher jobs!
